Ever heard of extreme ironing? Apparently, it "combines the thrills of an extreme outdoor activity with the satisfaction of a well pressed shirt." Some places where ironing has been done: the exact center of the Antarctic, 137m (450 ft) underwater, Mt. Everest, a nudist beach, in caves, while rock climbing, while jumping off a rock face, while hang gliding and while bog snorkeling. In case you are wondering, the irons are battery-powered. Here is a video of extreme ironing and here is a photo gallery from the official site.
